[Computer tomography in the evaluation of the status of the ventricular system of the brain in hydrocephalic children].

The authors analysed computer-aided tomograms of 182 children of different age with occlusive and open forms of hydrocephalus in the progressive, subcompensated, and compensated stages. The main signs characteristic of the various forms of hydrocephalus and stages of its clinical course were revealed. The VBR and Evans indices and the indices of the anterior and posterior horns and medial fossa were calculated and analysed and their correlation determined. The regular features in the dilatation of various parts of ventricular system were determined according to the changes of these indices. In some cases computer-aided tomography made it possible to identify the etiological factor in the development of hydrocephalus: three-dimensional structures, malformations of the brain, inflammatory processes.
